This was always in my mind, what happened when we start or restart sql server services from os service panel. There are long list of activities process out to get connected with database.

SQL Server Detecting Node configuration: node 0: CPU mask: 0x000000000000000f:0 Active CPU mask: 0x000000000000000f:0 for NUMA configuration. 8. Starting up database 'master' and do transactions rolled forward in database 'master' (1:0). 9. SQL Server Audit is starting the audits. 

When You have assigned a task to optimize a database or performance tuning of an application. Then there could be various dimensions to perform this task because slow performance of application could be many more which can not describe on single page but it can be summary in a table like below I found this table that shows database performance and slow running application performance dimension and there activity start procedures. Performance Dimensions Percentage Values Process Strength Activity Strength Remarks Application Design and Business process 25.00% Long Process Lower priority Module wise activity. Database Schema Design - Logical 15.00% Medium Follow best practices Required short downtime Module wise activity. Database Maintenance 15.00% Quick process Required on OLTP Short downtime weekly or monthly. Indexing 15.00% Quick process Required on OLTP Short downtime weekly or monthly Module wise activity. Server Hardware (CPU/Memory/other) 12.00% Medium process Follow
